decoye Posted October 14, 2021 Share Posted October 14, 2021 Hi, i am seeing an odd behaviour in cryptomatte support in affinity photo. i am rendering out a 32 bit exr file from my render package, in linear space. its a multilayer file, when i import it in affinity photo, the cryptomatte is transparent and almost not possible to make out that something is there, let alone i can seperate the objects. When i import same file into after effects and use the typical cryptomatte workflow, everything works as expected. here ist the test file. what am i doing wrong? I am using icc display transform as i have read up on the forum about that is the way to go in affinity photo, but other than this i dont know what i would be doing wrong...

Tom4D Posted October 14, 2021 Share Posted October 14, 2021 I'd say the problem is that Affinity doesn't really support Cryptomatte, unfortunately. But it would be great if it did. Quote Link to comment Share on other sites More sharing options...
decoye Posted October 14, 2021 Author Share Posted October 14, 2021 well, according to their youtube they support propper cryptomatte passes, with blender and or vray, so there must be something that i do wrong. Quote Link to comment Share on other sites More sharing options...
Tom4D Posted October 14, 2021 Share Posted October 14, 2021 Unfortunately just a lousy workaround that uses flood selections in the Cryptomatte preview channel to create masks. This has nothing to do with what Cryptomatte actually is, or how it works. Quote Link to comment Share on other sites More sharing options...

Tom4D Posted October 14, 2021 Share Posted October 14, 2021 Here is an example for a real Cryptomatte workflow (Not Affinity related of course): Quote Link to comment Share on other sites More sharing options...
Tom4D Posted October 14, 2021 Share Posted October 14, 2021 Don't know what the problem is on your side. I just testet your example and it works as you expect it: Quote Link to comment Share on other sites More sharing options...
decoye Posted October 14, 2021 Author Share Posted October 14, 2021 Damn. Interesting thing is, you get way more layers than me from the file. thats what i get... Quote Link to comment Share on other sites More sharing options...
Tom4D Posted October 14, 2021 Share Posted October 14, 2021 I think we are now on the trail of the mystery. 😎 That's because your preference "Color" settings. Uncheck "Associate OpenEXR alpha channels" That option is needed if you are using straight alpha instead of premultiplied alpha. decoye and Hans N. 2 Quote Link to comment Share on other sites More sharing options...
